Hi, I have a little experience with Excel but im stumped with this even after googling. I need a formula that does the following.

Formula Cell is located in A1

Cells H1, H2 & H3 will have either a true or false value. If one of them is true I need A1 to return a text string as listed below. Note only one of the H cells could have a true value.

H1 if true A1 would be abc (if false no text)
H2 if true A1 would be def (if false no text)
H3 if true A1 would be ghi (if false no text)
